The 40 reason engine burning oil "
12 piston ring bank breakage or fragmentation
The shore is broken or cracked piston rings, piston rings due to not embedded in the ring grooves, resulting in excessive oil from entering the combustion chamber. In addition, will also lead to completely damaged cylinder, piston and piston ring. So we should pay close attention to, once the signs must be replaced immediately.
13 valve rod or tube wear
If the valve rod and catheter wear, vacuum suction intake may produce the valve rod and the pipe between the oil and the oil vapor inhalation intake manifold, and ultimately into the combustion chamber to burn. If the situation did not improve, then when the engine to replace the new piston ring, because of the increase in inlet vacuum suction, oil consumption will increase; when the engine overhaul, originally attached after the valve rod and tube on the surface of sludge and sediments is cleared, gap will further increase, the oil leakage loss will become more obvious. For OHV type engine exhaust valve or the intake valve either, are likely to occur the phenomenon of the loss of oil. The valve guide clearance is too large due to high oil consumption problem can be improved through continuous dressing valve rod. Sometimes the new valve also need such dressing. The fastening type valve seal advanced (Bonded Valve Seal) can effectively prevent oil leakage loss.
